1. UNT Libraries TRAIL Processing Mark Phillips April 26, 2016

2. There are currently two processes for digitizing technical reports with TRAIL

3. The bulk of content goes to the University of Michigan for scanning by Google and inclusion in Hathitrust

4. There are some formats that are not sent to UMich

5. Reports with foldouts

6. Reports with Maps

7. Reports with other random parts

8. Microforms

9. Microfiche

10. Microcard

11. Maps

12. These items are scanned at the UNT Libraries in the Digital Projects Unit

13. The workflow

14. UNT receives boxes of new items from Arizona for scanning.

15. These arrive at the DPU and are processed by Lee Fulton and his students.

16. All reports come to UNT with a unique identifier assigned to them.
metadc303203

17. We remove the binding for the items that have been donated for destructive scanning

18. Items loaned that can't be cut are set aside in a different workflow

19. Lee and his students scan all of the pages of an item and all foldouts and oddly shaped pages

20. 600 DPI bitonal 400 DPI grayscale 400 DPI color

21. All uncompressed TIFF files

22. They align the pagination with the sequence of files

23. 0001.tif = Front Cover
0002.tif = Front Inside Cover
0003.tif = blank
0004.tif = blank
0005.tif = title page
0006.tif = blank
0007.tif = Page 1
0008.tif = Page 2

24. This is done so you can “jump to page 4, not image sequence 4”

25. 000100fc.tif = Front Cover
000200fi.tif = Front Inside Cover
tif = blank
tif = blank
000500tp.tif = title page
tif = blank
tif = Page 1
tif = Page 2

26. We use a local naming convention called “magicknumbers” for this.

27. Which also helps with the QC of the items.

28. Each report is verified to have all of the pages scanned.

29. A descriptive metadata record using the UNTL metadata schema is created partly from the supplied MARC record from Arizona and augmented with additional information.

30. PrimeOCR by Prime Recognition
Each tiff image is processed with Optical Character Recognition (OCR) software.

31. The RAW output is used so we have the coordinates of the words for highlighting later

32. A searchable PDF is created for each page along with the OCR output.

33. These pdfs are combined into a single PDF document for the report.

34. A finished report looks like this on the disc.

36. Reports are ingested into the UNT Libraries Digital Infrastructure in batches

39. Web scale images, pdf, and metadata are added to the UNT Digital Library into the TRAIL collection

40. Master files are added to the Coda Repository for preservation.

41. Once online physical reports are inventoried and discarded once verified to be online.

42. Loaned reports are returned to Arizona or the loaning insitution.

62. 2015 TRAC Self-Audit

63. In 2015 the UNT Libraries completed a self-audit using the Trusted Repository Audit & Certification (TRAC) framework

64. Full documentation for the self-audit is available via the UNT Libraries Website
Includes
Policies related to preservation, access, user feedback and usage
Content and partnership agreements
Detailed workflows and technical documentation

67. UNT Libraries continues to value the partnership we have with TRAIL and look forward to opportunities to expand our work to provide access to these resources for users around the world.
